Figure 4.25 Coast to Stop
Note: After a stop is initiated, any subsequent Run command entered will be ignored until the minimum baseblock time (L2-03) has expired. Do
not enter Run command until it has come to a complete stop. Use DC Injection at Start or Speed Search to restart the motor before it has
completely stopped.
Setting 2: DC Injection Braking to Stop
When the Run command is removed, the drive will enter baseblock (turn off its output) for the minimum baseblock time
(L2-03). When the minimum baseblock time has expired, the drive will inject the amount DC Injection Braking is set in
parameter b2-02 into the motor windings to brake the motor. The stopping time in DC Injection Braking to Stop is significantly
faster compared to Coast to Stop.

DC Injection Braking time is determined by the value set to b2-04 and the output frequency at the time the Run command is
removed. It can be calculated by:
DC Injection brake time
(b2-04) x 10 x Output frequency

Note: If an overcurrent (oC) fault occurs during DC Injection Braking to Stop, lengthen the minimum baseblock time (L2-03) until the fault no
longer occurs.
